学校给我分配了一个制作骰子游戏的机会,用户可以在其中改变骰子的眼睛,他们给我的唯一提示就是使用ASCII表。
到目前为止,这是我的代码,我正在碰壁,因为我如何使数字成为用户的输入(我不是很有创造力):
System.out.println("Which character should be used as the eye of the dice:");
char eyeDice = input.next().charAt(0);
System.out.println(eyeDice);
int Dice;
Dice = (int)(Math.random()* 6 + 1);
while (Dice < 6) {
Dice = (int)(Math.random()* 6 + 1);
System.out.println(Dice);
}
代码输出如下:
Which character should be used as the eye of the dice:
$
$
1
4
1
1
1
1
4
1
2
2
6
Process finished with exit code 0
这应该是最终的样子:
Which character should be used as the eye of the dice:
#
#
#
# #
#
# #
# #
# #
# #
# #
Process finished with exit code 0
任何朝着正确方向的提示或提示将不胜感激!

计算机没有附带将数字“ 4”转换为ascii图形的代码。
您必须自己编写。我建议将它们画在一张纸上。在您的Java代码中,您可以有一堆if / elseif语句,每6个面中有一个。每个块将打印3行。首先锁定要用于眼睛的角色,然后再进行制作,以便用户以后可以配置。
这是您入门的一部分:
if (dieRoll == 5) {
System.out.println("* *");
System.out.println(" * ");
System.out.println("* *");
} else if (dieRoll == 6) {
// you figure it out from here...

在给定的示例中,eyeDice
是'#'
。并且抛出的dice
(在Java中请加上一个小的d
)将是3、5、4和6。
因此,您需要使用以下方法:
void printDice(int dice, char eyDice) {
... System.out.println ...
}
和您的代码
int dice = (int)(Math.random()* 6 + 1);
while (dice < 6) {
printDice(dice, eyeDice);
dice = (int)(Math.random()* 6 + 1)
}
将打印出5(忽略眼睛):
System.out.println("? ?");
System.out.println(" ? ");
System.out.println("? ?");

这不是一个完整的示例,但可以让您知道该怎么做
public static void main(String[] args){
System.out.println("Which character should be used as the eye of the dice:");
char eyeDice = input.next().charAt(0);
System.out.println(eyeDice);
int Dice;
Dice = (int)(Math.random()* 6 + 1);
while (Dice < 6) {
Dice = (int)(Math.random()* 6 + 1);
System.out.println(Dice);
//If statement calling print
}
}
private void printOne(char character){
String dice = "\n # \n";
System.out.println(dice.replace('#', character));
}
private void printTwo(char character){
String dice = "# #\n\n# #";
System.out.println(dice.replace('#', character));
}
private void printThree(char character){
String dice = "#\n #\n #";
System.out.println(dice.replace('#', character));
}

我知道您已经有了答案,但是另一种可能的解决方案是使用ENUM。例如:
public class Dice
{
private enum DieFace
{
ONE('1', " \n * \n "),
TWO('2', "* \n \n *"),
THREE('3', "* \n * \n *"),
FOUR('4', "* *\n \n* *"),
FIVE('5', "* *\n * \n* *"),
SIX('6', "* *\n* *\n* *");
private char characterCode;
private String representation;
DieFace(char characterCode, String representation)
{
this.characterCode = characterCode;
this.representation = representation;
}
public static DieFace getDieFaceFromCharacterCode(char characterCode)
{
DieFace dieFaceFound = null;
for (DieFace dieFace : values())
{
if (dieFace.characterCode == characterCode)
{
dieFaceFound = dieFace;
break;
}
}
return dieFaceFound;
}
@Override
public String toString()
{
return this.representation;
}
}
public static String getDieFaceFromCharacter(char characterInput)
{
DieFace dieFace = DieFace.getDieFaceFromCharacterCode(characterInput);
return dieFace == null ? null : dieFace.toString();
}
}
这是对课程的测试:
public class DieTest
{
@Test
public void testGetOne()
{
String expectedResult = " \n * \n ";
assertEquals(expectedResult, Dice.getDieFaceFromCharacter('1'));
}
@Test
public void testGetTwo()
{
String expectedResult = "* \n \n *";
assertEquals(expectedResult, Dice.getDieFaceFromCharacter('2'));
}
@Test
public void testGetThree()
{
String expectedResult = "* \n * \n *";
assertEquals(expectedResult, Dice.getDieFaceFromCharacter('3'));
}
@Test
public void testGetFour()
{
String expectedResult = "* *\n \n* *";
assertEquals(expectedResult, Dice.getDieFaceFromCharacter('4'));
}
@Test
public void testGetFive()
{
String expectedResult = "* *\n * \n* *";
assertEquals(expectedResult, Dice.getDieFaceFromCharacter('5'));
}
@Test
public void testGetSix()
{
String expectedResult = "* *\n* *\n* *";
assertEquals(expectedResult, Dice.getDieFaceFromCharacter('6'));
}
@Test
public void testGetInvalid()
{
// < 1 is invalid
assertNull(Dice.getDieFaceFromCharacter('0'));
// invalid character (non-number)
assertNull(Dice.getDieFaceFromCharacter('a'));
// > 6 is invalid
assertNull(Dice.getDieFaceFromCharacter('7'));
}
}

如果您希望最大程度地减少重用,则可以使用switch语句。例如:
public class Dice
{
private static final String LINE_BREAK = "\n";
public static String getDieFaceFromCharacter(char characterInput)
{
String top = " ";
String middle = " ";
String bottom = " ";
switch(characterInput)
{
case '5':
top = "* *";
bottom = "* *";
case '1':
middle = " * ";
break;
case '3':
top = "* ";
middle = " * ";
bottom = " *";
break;
case '2':
top = "* ";
bottom = " *";
break;
case '6':
middle = "* *";
case '4':
top = "* *";
bottom = "* *";
}
return top + LINE_BREAK + middle + LINE_BREAK + bottom;
}
}
